What does boy band sensation One Direction have in common with alt-rock-era stars Veruca Salt and R.E.M.? They're all among the acts who revealed that they'll be participating in the 2014 edition of Record Store Day, a promotional event geared toward getting consumers to shop at participating indie retailers.

A now annual affair in which artists big and small release limited-run editions of rare or hard-to-find pieces, the full slate of participants will be unveiled on Thursday during a news conference at Hollywood's Amoeba Music. Public Enemy's Chuck D is scheduled to be on hand, as is L.A. Mayor Eric Garcetti.

Yet for most fans and collectors, the stars of April 19's Record Store Day are clearly the products.

Monday brought the news that the complete original lineup of Chicago's high-powered rock act Veruca Salt has reunited and will unleash its first new material in more than a decade. Two songs -- “The Museum of Broken Relationships” and “It’s Holy” -- will be issued on a slab of 10-inch vinyl that will also include radio hit "Seether." The 10-inch will be published by Minty Fresh, Veruca Salt's early record label.

R.E.M., meanwhile, will release a 4-LP "Unplugged" set, which will capture the band's two appearances on the popular MTV series, one in 1991 as a full band and one in 2001 without founding drummer Bill Berry. Rhino will publish the collection, which will include songs not aired on the original broadcasts.

Already plenty of other acts have also unveiled Record Store Day exclusives in advance of Thursday's news conference. Soundgarden, celebrating the 20th anniversary of "Superunknown," will release to indie stores only a set of five limited edition 10-inch vinyl records dedicated to "Superuknown's" singles and B-sides.

The Sex Pistols are prepping a small set of 7-inch vinyl that will showcase "alternate takes" of "Never Mind the Bollocks," "Here's the Sex Pistols" and "Belson Was a Gas." Indie label Sub Pop has a number of releases planned, including a live recording of Mudhoney's 2013 performance on top of Seattle's Space Needle, to be released on vinyl.

That's just a scratching of the surface. The full slate will be revealed at 10 a.m. at Amoeba. Also on hand for the festivities will be John Densmore of the Doors and a number of local record shop owners. After Garcetti issues a proclamation to commemorate Record Store Day, ditch work and watch a small round-table discussion on the history of the event.
